## What is Unagent?

See how your site behaves in various browsers by tweaking the user agent.

NOTE: Websites may still use fingerprinting techniques to determine what browser you are using. Unguent does not actually change the browser engine used by Safari.

The user agent tells a website what browser (including the version) you are currently using. By detecting the user agent, websites can change their behavior appropriately (such as by disabling features where not supported).

Features
- Choose from a set of preset user agents, or add and manage your own presets
- Set a user agent as a global user agent, or set user agents per site
- Update preset user agents

Unagent does not collect any data, and only rewrites the User-Agent header where necessary.

## Key features

- Switch user agents
- Preset user agents
- Custom user agents
- Site-specific user agents
- Add custom presets

### 2/5 — Decent Safari Plugin

*2026-05-19, version 1.10*

Unfortunately doesn’t work for many sites. It truly only allows you to change the User-Agent header for your web requests. Many sites nowadays also check User-Agent Client Hints, which this plugin does not alter, and still causes sites to present the mobile version.

### 5/5 — Very Nice!!!

*2026-04-20, version 1.10*

Just works perfectly.  Awesome to have an app like this for iPhone.  Love it!!!

### 2/5 — Not Work 動作しません

*2026-02-17*

Safariで動作しませんでした
It wasn’t working (iOS 26.3)

### 1/5 — App crash

*2026-02-02, version 1.8.2*

The app crashes every time I try to create a user agent profile. Unusable

### 5/5 — Great Jon

*2025-12-19, version 1.8.1*

Perfectly adapted to my iPad Mini, giving the small-screen tablet the same experience as a phone.

### 1/5 — Didn't work

*2025-12-15, version 1.8.1*

Didn't work to display Yahoo mail desktop version in iOS Safari, despite trying multiple preset desktop user agents. Also, the app description and privacy section say it doesn't collect any data, but it seems to require a permission toggled on giving access to webpage content itself to work.

### 5/5 — Works great now!!

*2025-11-24, version 1.8.1*

Has helped me deal with some pesky websites. Biggest problem is Disney+, would help if there were windows options

Edit - Props to the dev, Disney now works!!! Can finally watch with an ad blocker on

### 5/5 — Does what it says

*2025-09-26, version 1.7.2*

This will pay for itself with just one booking on Priceline, which charges several dollars per night more if you have a safari string in your browser. You can even toggle it on/off delete cookies, and watch it throw back different prices.

### 5/5 — Essential Safari Extension for Apple Web Debuggers

*2025-08-16, version 1.6.3*

This app is a game-changer for Apple users and developers alike! The Safari User-Agent Extension works seamlessly, providing an excellent browsing experience. It’s perfect for debugging and enhances functionality effortlessly. Highly recommend for anyone looking to optimize their Safari usage. Five stars all the way!

Looking forward to future updates where quick tools within the Safari extension modal become even more accessible.

### 5/5 — The App To Use

*2025-06-01, version 1.6.3*

This is the best agent switching Safari extension on the App Store

## Frequently asked questions about Unagent

### What does this app do?

This app allows you to change the user agent string your browser sends to websites. The user agent identifies your browser and its version, and by modifying it, you can see how websites behave differently across various browsers and their versions.

### What are the key features?

Key features include choosing from a set of preset user agents, using presets as a global setting or pasting your own custom user agent, and setting specific user agents for individual websites. You can also add your own custom presets.

### Is this app free to use?

Yes, this application is free to use. It does not have any in-app purchases or advertisements, and it does not collect any user data.

### How can I use this app to test a website?

You can use this app by selecting a preset user agent that matches the browser you want to test with, or by creating and applying your own custom user agent. You can then navigate to the website you wish to test and observe how its content or functionality changes based on the altered user agent.

### Can this app guarantee accurate website testing?

While this app effectively changes the user agent header, it's important to note that websites may still employ fingerprinting techniques to identify your browser. Therefore, the results should be used as a guide, and not as a definitive measure of browser compatibility.
